Over the past few years, the talent on the Bishop O’Dowd High girls basketball team has caught the attention of college coaches from all over the country.

Now four seniors from the defending Division III state champions are officially headed to NCAA Division I programs.

Oderah Chidom, K.C. Waters, Breanna Brown and Ariell Bostick will go in separate directions next year, but signed their letters of intent together in a ceremony at the school Wednesday, the first day of the early signing period for all sports except football, soccer, track and field, cross country and men’s water polo.

Chidom, a 6-foot-4 forward who is ranked a top-10 recruit by three rating services, is headed to Duke. Brown, also a 6-4 forward, will join her in the Atlantic Coast Conference after she signed with Virginia Tech.

Waters elected to play at Cal, and Bostick will join San Diego State.

“It feels real, now I can actually see myself at the next level,” said Chidom, who played for the U.S. under-17 national team over the summer. “It just feels like it’s the real deal now. I’m trying to enjoy every moment.”

Chidom is part of a recruiting class at Duke that was ranked No. 2 in the nation by Blue Star Report.

Waters, who’s 6-2, turned down offers from schools such as Tennessee and Florida to play for Lindsay Gottlieb at Cal. She said ex-Dragons teammate Mikayla Lyles, now at Cal, helped convince her to go to Berkeley.

“I know I made the right decision and to make it official feels great,” said Waters, the 2012 East Bay Player of the Year.

In boys basketball, Salesian’s Jabari Bird, Deer Valley’s Marcus Lee and De La Salle’s Elliott Pitts all made their college choices official, with Bird headed to Cal, Lee to Kentucky and Pitts to Arizona.

Lee, ranked the No. 30 overall prospect in the nation by ESPN, announced his oral commitment to Kentucky on Oct. 17, choosing the Wildcats over Cal. He joins a Kentucky recruiting class that ESPN has ranked No. 1.

Pitts, a 6-5 shooting guard, is the No. 91-ranked prospect in the nation by ESPN. He’s part of a recruiting class that ESPN ranks No. 18.

“I’m really excited just to finally know I’m definitely going to Arizona and get this thing going,” Pitts said.

It was also signing day for baseball, boys and girls lacrosse, boys and girls swimming and girls volleyball, among others.

Three members of Campolindo’s baseball team — Trent Shelton (Oregon State), Brett Stephens (UCLA) and Robbie Tenerowicz (Cal) — signed Wednesday. Also headed to Cal is De La Salle’s Andrew Buckley. Joining Stephens at UCLA is Steven Farinaro of Head-Royce and O’Dowd’s Dominic Miroglio.

Campolindo’s Sven Campbell, the 2012 East Bay Boys Swimmer of the Year, signed with Cal, and teammate Steven Stumph signed with USC. Other boys swimmers headed to Division I schools are San Ramon Valley’s Cody Tanabe (Cal Poly) and Clayton Young (UC Santa Barbara), Miramonte’s Charlie Wiser — who’ll swim and play water polo at Stanford — and Heritage’s Ryan Barsanti (Wisconsin).
